IR3513ZMTRPBF
FEATURES
• 0.8V reference supports 0.8V to 5.1V output voltage with +/-0.5% system set point accuracy
• Dynamic margin function provides ± 5 % reference offset
• 1 (stand-alone) to X phase operation with additional Phase IC
• Programmable 250 KHz to 9 Mhz daisy-chain digital phase timing provides a per phase switching
frequency of 250 KHz to 1.5 MHz with no external components
• Differential remote sense amplifier with 100kohm input impedance
• IC bias linear regulator control with programmable output voltage and UVLO
• Programmable converter current limit during soft-start, hiccup with delay during normal operation
• Over voltage protection communicated to Phase ICs
• System over voltage signal protects against failures such as a shorted high side MOSFET
• Detection and protection of open remote sense lines
• Open control loop protection
• 7V/2A gate drivers (4A GATEL sink current)
• Integrated boot-strap synchronous PFET
• Small thermally enhanced 32L 5 x 5mm MLPQ package
